Beginning with WebSphere® Application
Server for z/OS® Version 7.0,
the load modules are in the product file system. You can use the switchModules command
to switch a configuration between using load modules in the file system
and using load modules in a dataset.
Note: The server_dlls_in_hfs environment variable
must also be set to 0 for the server to use the DLLs
that have been put into a dataset that is in STEPLIB, LPA, or link
list.
Location
The switchModules.sh shell
script is located in the smpe_install_root/bin or app_server_root/bin directory.
